IMPROVEMENT IN PAPER-FILES.

More- The Schedule referred to in these Letters Patent and making partof the same.

To all whom 'it may concern:

Beit known that we, J con P. TIRREL'L, of Charles; town, county ofMiddlesex, and State of Massachusetts, and H1RAM WHITNEY, of Watertown,county and State'aforesaid, have invented an improved Paper- File, andthat the following is a full, clear, and exact description thereof',reference being hadto the accompanying'drawings, in which- Figure l is afront view of our file.

Figure 2 is a back view of same.

The object of our invention is to produce a .bill or paper-file whichshall conveniently hold papers, while it presents means for computingaccounts and making memoranda.'

The nature of our invention consists in a board having a clamp held bysprings, and a tablet and slate upon the back of the board.

In the drawings- A is a board, of .proper dimensions.

B, a clamp, or clasp. In fig. 1, thisv clamp B is shown as raised forthe insertion of papers.

c and c are wires running along the sides of board A, attached to theboard at K K and m m. I

A wire, b, is bent around wires c c', and extends over clasp B, andholds clasp B by staples S S, or equivalents. v

The wire b is bent at b over a hole in clasp B.v

d d are wires bent around wires b b, at the side of the clamp B,'andattached to board A,at the foot, the wires terminating in coil-springstl d".

h is a tongue, under bend b', to prevent too much action of wire b.

e is simply a ring, or staple, serving as a handle. VThe Wires c c arebent, as shown at K K.

Now, when the clamp B is drawn up, as shown in iig. l, the wires b holdon the curve of wires c c at papers.

The advantage of this construction over others is that when the clasp Bis down there are no wires and joints projecting from the board A,butall is smooth.

We put upon the back the erasable tablet D and slate surface F. Theadvantage of this is apparent, for collectors and others often want tomake some memorandum, or cast up accounts, &c., and this gives theconvenient means.

We attach loops l i, for holding pencils.

What we claim as our invention, and desire to secure by Letters Patent,is

In combination, the board A, wires c db d, springs d d, and clasp B, thewhole making a paper-hie, substantially as described and specified.

In testimony whereof, we have signed our names to this specification, inthe ,presence of two subscribing witnesses.
